PARING KNIFE AND GAGE- SPECIFICATION forming part of Letters Patent No. 783,053, dated February 21, 1905. Application filed December 7, 1904- Serial No. 235,904.

1'0 alt whmn it may concern.-

Be it known that I, J OSEPI-I F. LAMB, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Paring Knives and Gages, of which the following is a specification.

My invention relates to improvements in paring knives and gages; and the objects of my improvement are simplicity and economy in construction with convenience and efficiency in use.

In the accompanying drawings, Figure 1 is a side elevation of my knife and gage. Fig. 2 is an edge view of the same. Fig. 3 is a side elevation of the knife with the gage detached. Fig. 4 is a detached side elevation of the gage. Fig. 5 is a side elevation of my knife and gage with the gage applied in left-handed position. Fig. 6 is a like view of the point end of the blade and gage with one of cesses omitted.

The knife-blade A and its handle B may be of any ordinary construction as to their general form. I form a perforation 6 in the blade near its heel end and a similar projection 7 near its point. These perforations are preferably rectangular and slightly longer than wide. At that edge of the perforation 7 which is nearest the back of the knife-blade I form two locking-recesses 8 and 9.

The gage C consists of a detachable piece of sheet metal having a body of any desired width and general form and with a short lug 10 at one end of the said body and a longer lug 11 at the other end. One edge of the gage C is in the form of a curved gage-bar 12 and is designed to project a little distance beyond the cutting edge of the knife blade, while its curved inner face extends parallel to the said cutting edge in the longitudinal direction and stands a distance therefrom corresponding to the thickest paring that the gaged knife will pare. Adjacent to this gage-bar 12 is an opening or slot 13, through which the parings may pass. Both of the lugs 10 and 11 are offset at their junction with the body of the gage a the locking-redistance substantially equal to the thickness of the knife-blade.

When a right-handed knife is desired, the handle is placed toward the right, and the long lug 11 of the gage is inserted in the perforation 7 and the gage C placed on that side of the blade that faces the operator. When the gage is forced toward the point of the blade as far as the offset lug 11 in the perforation 7 will permit, the short lug 10 may be forced side wise through the perforation 6 far enough to carry its end to the opposite broad side of the blade. The gage may then be forced bodily toward the handle until its movement in that direction is stopped by the wall of the perforation 6 and the offset portion of the lug 10. At this time the long lug, if of the proper length, will still have its end in engagement with the knife-blade on one side, while the body of the said gage 'lies on the opposite side of the blade, so that the said gage will be thus held in position fairly well without any additional fastening. I prefer, however, to provide an additional lock against moving the gage longitudinally, and for this purpose I form the locking-recesses 8 and 9, one for a right-handed knife and the other fora left-handed knife. The recess 8 when the gage is applied for righthand use comes directly opposite the offset junction of the lug 11 and body of the gage, and by moving that end of the gage edgewise toward the back of the knife-blade, as shown in Fig. l, the gage is positively locked against being moved longitudinally to disengage it from the blade. To detach the gage C, its outer end is first moved edgewise to disengage the offset from the recess 8, then slipped bodily endwise to bring the short lug 10 into register with the perforation 6, then that end of the gage is pulled away from the blade, and, lastly, the gage is pulled off, withdrawing the long lug 11 from the perforation 7.

For use with the left hand the operator turns the handle toward the left and places the gage on the nearest side of the blade by passing the long lug endwise into the heel perforation and the short lug sidewise through the point perforation 7. If without a locking-recess, the gage may now be moved bodily endwise, so as to bring the ends of both lugs against the opposite side of the blade from that occupied by the body of the gage. If both of the notches S and 9 are present, the point end of the gage is moved edgewise toward the back of the knife to force the offset portion of the lug 10 into the locking-recess 9, as shown in Fig. 5. The gage, however,

may be locked when only the locking-recess 8 is employed by merely forcing the outer end of the gage edgewise toward the back of the blade without moving the gage endwise, all as illustrated in Fig. 6.

1 am aware that a detachable paring-gage for substantially an ordinary knife-blade is old, and the same is hereby disclaimed. In

my improvement there is only one gage-barits opposite ends, and the detachable gage having a gage-bar and offset lugs at each end of its body for engaging the said blade when extended through the said perforations, with the body of the said gage resting against one side of the said blade, and the ends of the said offset lugs resting against the opposite side of the said blade.

2. The herein-described knife and gage, comprising the blade having perforations at its opposite ends, and the detachable gage having a gage-bar, a long offset lug at one end of its body, and a shorter offset lug at the opposite end of the said body for engaging the blade when extended through the said perforations.

3. The herein-described knife and gage, comprising the blade having perforations at its opposite ends, and the detachable gage having a gage-bar and ofiset lugs at each end, one of the said perforations in the said blade having a locking-recess at one edge for being ongaged by the offset portion of one of the said lugs.
